Document Summary
September 17th 2015: to culture microbes in a laboratory, it is necessary to supply all nutrients, nutrients are compounds of chemical elements that can be used by the cell required for growth to support growth and metabolism. Substance that is taken up by the cell. 2 types of metabolic reactions; catabolic and anabolic reactions. Anabolic - bring things up: macronutrients are required in large amounts, micronutrients are required in trace amounts (typically <0. 01% total mass) Not needed in a large amount (trace amounts: use a lot of protein (55%) ; a lot of different uses with protein in a cell, rna is also important and essential in a cell (20. 5%) Culture media: nutrient solution used to grow microorganisms in the laboratory, defined media contain precise amounts of pure chemicals in distilled water. Break down all the compositions in order to know how much chemical compounds are within the media.
